4 months ago I got some Bluetooth LE error in logcat, so I disabled the GATT in aosp_rpi4_car.mk, and re-tested. But did not help.

I try to build one car (AAOS) image following those steps below (using r22 as a sample). The AAOS on Pi4 (8G RAM) could startup, and could pair with a Pixel 3(Android 12), or iPhone 14 (iOS 16).
When I try to start up the dialer app or bluetooth media app, "connect to a Bluetooth device" shows up on the screen. And cannot hear anything through the 3.5mm headset on Pi4, when playing music on those Phones
On Pixel 3, playing some music, and adjust the volume, I can see the bluetooth icon on the volume bar. On iPhone, I do select the Pi4 as the "speaker".
I noticed #33 and https://github.com/raspberry-vanilla/android_device_brcm_rpi4/pull/2. And the modification of "aosp_rpi4_car.mk" has been merged into "android-14.0.0_r22".
So, how can I solve this problem?
Hardware: Pi4 8GB RAM, type-C port to PC USB3, HIMD0 to a PC monitor, no extra power supply, Logitech wireless mouse.
